When it crashes does the computer go compleatly off? How long does it stay on before it crashes and does it crash only during certain times or with certain programs. If you are getting no blue screen of death then my main guess is the CPU is overheating or a power supply problem.

no the mobo lights stay on,

and this is new, when i restart, the keyboard lights blinks and there is sound from the case ,like revving .

no BSOD, temp is at 50-60 range

Then there is something wrong. Either the CPU isn't in right, the heatsink isn't on right or the RAM sticks aren't fully seated.
